I listened the the candida diet people for nearly 2 years about coffee being a bad thing. Previously, I wouldn't touch it with a 10 ft. pole.

I have determined that it causes me no upset whatsoever, and I am very, very sensitive to eating the wrong things such as too much sugar, grain, starch. I now enjoy a cup of coffee nearly every morning, I just make sure to buy low acid or acid reduced coffee. I don't sense that the coffee causes me any flare-up at all.

Trader Joes has a low-acid (steam processed) dark roast. There are a couple of others such as Hevla or Ecuatorial Coffee who make this specially processed coffee where they steam off the contaminents from the outer shell of the bean which is where they say the gastro-irritating properties lie.

Just my view.

Here's the story with coffee.
When it is poured into the body, the body reacts by doing what is needed to handle this poison.
Many different hormones including adrenalin are excreted.
The body basically gets revved up in this process.
All this inner activity causes one to be more awake.
Its a little like your riding with a friend in a car and all of a sudden he/she floors the gas peddle. Its going to make you more alert with this activity.
When the activity runs its course, the body feels drained from the exertion.
Yes coffee is addictive.
For one, its a poison to the body. The only thing we can get addicted to is a poison.
Nobody has ever gotten addicted to celery or lettuce.
The other addicting factor is the adrenalin rush.
By the way, coffee drinking is very rough on the liver. The liver is involved with this handling of a poison.
Ever notice that Starbucks coffee is a little more addictive than most.
The beans are processed in such a way as to give your body more of a kick. But the real kick comes from what your body has to do in response to drinking it.
Once the body gets worn down from repetitive poison consumption the kick becomes less and less and more and more poison is required to produce an equal effect.
